See what our community has to say about using Sutro...
"It works. It keeps me on top of my pool, which I think results in less chemicals. It's easy!" - Bill Moreland
"Saves me trips to get water checked and also let’s me tell my daughter who lives near by what needs to be done when I’m away, so the pool doesn’t get out of wack when I’m not there." - Ric
"Accurate and daily measurements, much better than anything I can accomplish with a test strip." Miguel L
